San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
Are Cats Good at Keeping Rats Away?
When it comes to removing rats from homes, the use of cats in hunting these rodents is one of the best natural ways of getting that done. Cats and rats are natural enemies; hence cats are good at keeping rats away. The only issue with keeping cats to remove rats from your home is that there is a high probability of it being prone to catching other non-target animals like frogs, birds, and lizards. Also, there are no guarantees that the cat you bring into your home to keep rats away will help catch the rat within a specific time.
Apart from the hunting skills that cats use to remove rats, the scent of a cat will also make rats stay away from your home. Rats have a well-developed sense of smell and can easily pick up slight scents. With this, they can sense the presence of a cat in a particular area and stay as far as possible away from it. This survival instinct of rats will send them packing.
But for this to work the way you want it to, you need to find a cat that displays typical hunting behavior. Naturally, cats do have hunting instincts and the urge to catch rats. But this only gets triggered when the right environment is in place or the cats are encouraged to do so.
If you want a cat with a good hunting instinct, the first thing you need to do is to make inquiries as to whether the mother of the kitten was a good hunter or not. Cats learn the required hunting skills from their mother. If you want the cat you will be introducing into your home to be a good hunter, it will need to learn these hunting skills from its mother.
